by Peer-Axel Kroeske, DL2LBP Apart from 549.0000, it seems like 7 offsets can be received 24h (though the afternoon is missing here). 4 of them belong probably to RNE (Spain), 2 could be Romania. Twoje Radio from Poland with two transmitters is probably inactive. Here are the guessings, based on earlier easurements from remote receivers (see last measured column).
